So here's why I think Dixie Kong is more likely to be an Echo than a Semi-Clone or Unique:
It all has to do with one single thing:
the Skeletons. Not the October spooky kind, but the actual model of the characters to base off of. All of the Echoes are easily able to be implemented into another character's skeleton given some slight adjustments for things like height. However, I find that something that causes disjoints can just kinda **** everything over, which is how I think Isabelle ended up differently. Her limbs are shorter than Villager, and that would make for some wonky animations and hitboxes, which even if a move is different, those similar moves
should have the same hitbox. If it doesn't look right because of the character model itself, it's more worthwhile to make her her own character rather to spend extra time tackling this extra problem when the former solution is just as time consuming.
Dixie Kong is pretty much a girl Diddy Kong. Put on a ponytail instead of a tail, put on a beret, lipstick and gum that up, and there isn't much needed left. It's easy, it's simple, and it saves production time.
Isabelle is an odd one out. If anything, that decreases Dixie's likelihood than increases it. And don't even say "
it's not in her character!!!" or "
b-b-but she doesn't do that in the dk games sakurai would never!!!", because I'm gonna take you hostage and make you play Metroid Prime 2 and 3
